Never connect the Off-Grid CyboInverter to the AC grid.
Doing so will damage the unit and void the warranty.
Only qualified personnel should install or replace
CyboInverters.
Perform electrical installations in accordance with NEC,
ANSI/NFPA70, and local electrical codes and practices.
The aluminum enclosure of the CyboInverter can reach
85°C (185°F). Do not touch!
The CyboInverter must be earth-grounded in accordance
with national and local electrical standards.
Never connect or disconnect any DC or AC connectors of
the inverter without first disconnecting the AC loads.

Build a separate “Off-Grid AC Circuit” for connecting to a
heating element of the electric water heater.
Use this CyboInverter for powering electric water
heaters or heating elements only.
The Off-Grid CyboInverter may send a small test signal
periodically to the “Off-Grid AC Circuit”.
Special protection against lightning strike may be required
to meet certain local and national standards.
Do not attempt to repair the CyboInverter. It contains no
user-serviceable parts.
If the solar panel is in the sun, there will be DC voltage
output. Be careful.

This photovoltaic rapid shutdown equipment (PVRSE) does
not perform all of the functions of a complete photovoltaic rapid
shutdown system (PVRSS). This PVRSE must be installed with
other equipment to form a complete PVRSS that meets the
requirements of NEC (NFPA 70) section 690.12 for controlled
conductors outside the array. Other equipment installed in or on
this PV system may adversely affect the operation of the
PVRSS. It is the responsibility of the installer to ensure thatthe
completed PV system meets the rapid shutdown functional
requirements. This equipment must be installed according to the
manufacturer’s installation instructions.
For roof mount PV systems, install the inverter within 1 foot
of the PV solar panel array. The Inverter enclosure to panel
substrate must have at least 0.5 inch (12.7 mm) open space.

CyboInverter H Model Q & A - 1
Yes. You have to disconnect the grid AC from
the heater. Otherwise, the grid AC can damage
the CyboInverter.
Can I use the H model for
single-element electric
water heaters?
1
You should add a thermostat. This will allow
you to switch off the grid power. Contact us for
more detailed suggestions.
My heater has 2 elements
but only 1 thermostat. What
can I do?
2
The following settings are examples:
Upper Thermostat = 98-100ºF (37-38 ºC)
Lower Thermostat = 135-140ºF (57-60ºC)
Hot water circulates upwards so the Upper
Element does not turn on if temp is higher than
the setpoint, resulting in electricity savings.
How do I set the temp
setpoints for the upper and
lower thermostat?
3
Yes. Just make sure the inverter output and
grid AC are not connected.
Can I use this for tankless
electric water heaters?

A number of states in the US may have adopted the NEC
2014 / 2017 690.12 codes.
Install an Outdoor AC Switch Box
Install an Outdoor AC Switch Box
Install an outdoor AC Switch at a suitable location, typically on
the wall near the Electric Service Panel.
Connect the AC output of the inverter to the AC switch and then
run the AC wire to the load of your off-grid circuit.
Label the AC Switch accordingly.
NEC 2014/2017 690.12 codes require Rapid
Shutdown of PV Systems. This switch can
shutdown the inverter immediately once it is
moved to its Off position.
Step 2. Install an Outdoor AC Switch

The 2 hot lines
of the
CyboInverter
output are equal.
They are both
black wires.
Step 3a. Wire AC to the Heater
If the inverter is mounted inside, connect its 2
output wires to an AC switch and then connect to the
lower element of the water heater through its electric
junction box on the top.
To comply with Rapid Shutdown, inverter
should be installed outside.

Step 3b. Wire AC to the Heater
If the CyboInverter is mounted outside, connect its 2 output lines to
an outdoor AC J-box and connect to the Outdoor AC Switch for
Rapid Shutdown. Then, connect the AC wires to a switchable AC
outlet or an AC switch installed inside. Finally, connect the output
wires to the lower heating element of the electric water heater.
The 2 hot lines of the
Inverter output are equal.
They are both black wires.
